Indima yee-ICs zeHolo zeMpembelelo kwiMoto ye-BLDC
Ii-ICs ze-Holo zempembelelo zidlala indima ebalulekileyo kwii-motor ze-BLDC ngokubona indawo ye-rotor, ivumela ukulawulwa ngokuchanekileyo kwexesha lokuhamba kwangoku kwiikhoyili ze-stator.
I-BLDC MotorUlawulo
Njengoko kubonisiwe kumzobo, inkqubo ye-BLDC yokulawula i-motor iyaqaphela indawo ye-rotor ejikelezayo kwaye emva koko iyalele umqhubi wokulawula i-motor ukuba atshintshe okwangoku kwi-coil, ngaloo ndlela eqalisa ukujikeleza kwemoto.
Ukufumanisa indawo ye-rotor yinxalenye ebalulekileyo yale nkqubo.
Ukungaphumeleli ukufumanisa indawo ye-rotor kuthintela isigaba samandla ukuba siphunyezwe ngexesha elichanekileyo elifunekayo ukuze kugcinwe ubudlelwane obufanelekileyo be-flux phakathi kwe-stator kunye ne-rotor, okubangelwa ukuveliswa kwe-torque engaphantsi.
Okona kubi kakhulu, i-motor ayiyi kujikeleza.
Impembelelo yeholo ye-ICs ibona indawo ye-rotor ngokuguqula i-voltage yabo yokuphuma xa ibona i-magnetic flux.
Ukubekwa kweHolo ye-IC kwi-BLDC Motor
Njengoko kubonisiwe umzobo, ii-ICs ze-Hall effect ezintathu zihanjiswa ngokulinganayo kwi-360 ° (i-angle yombane) ye-rotor.
Izibonakaliso eziphumayo ze-ICs ze-Hall effect ezintathu ezibona utshintsho lwemagnethi ye-rotor ngokudibanisa yonke i-60 ° yokujikeleza malunga ne-360 ° ye-circumference ye-rotor.
Le ndibaniselwano yemiqondiso itshintsha ikhoyo ngoku equkuqelayo kwikhoyili. Kwinqanaba ngalinye (U, V, W), i-rotor inamandla kwaye ijikeleza i-120 ° ukuvelisa i-S pole / N pole.
Umtsalane wamagnetic kunye ne-repulsion eyenziwa phakathi kwe-rotor kunye ne-coil kubangela ukuba i-rotor ijikeleze.
Ukuhanjiswa kwamandla ukusuka kwisekethe yokuqhuba ukuya kwikhoyili kulungelelaniswa ngokwexesha lokuphuma kwesiphumo seHolo ye-IC ukufezekisa ulawulo olujikelezayo olusebenzayo.
Yintoni enikayoiimotor zokungcangcazela ezingenabrushlessubomi obude? Ukusebenzisa i-Hall Effect ukuQhuba iiMoto zeeBrushless. Sisebenzisa i-Hall Effect ukubala indawo yemoto kwaye utshintshe isignali yokuqhuba ngokufanelekileyo.
Le mifanekiso ibonisa indlela isignali ye-drive etshintsha ngayo kunye nemveliso evela kwi-Holl Effect sensors.
Thetha neeNgcali zakho zeNkokeli
Sikunceda ukuba uphephe imigibe yokuhambisa umgangatho kwaye uxabise imfuno yemoto yakho encinci ye-brushless, ngexesha kunye nohlahlo lwabiwo-mali.
